monitor_work is used to end(abort) all dying ubqs and cleanup device. With recovery feature enabled, we reinit dying ubqs in START_USER_RECOVERY command and we do not cleanup ublk device. So scheduling monitor_work in START_DEV is unnecessary. We manually schedule monitor_work in STOP_DEV regardless reocvery feature is enabled or not. So we can cleanup everything in the end.
